Abstract
Official abstract text for this publication.
An ONU includes a power-interruption detecting unit configured to detect power interruption of the ONU, a transmitting and receiving unit capable of being set in a power saving state, and a PON-side control unit configured to notify an OLT of, as power saving return information, a power holding time during occurrence of the power interruption of the ONU and a startup time, which is time until the transmitting and receiving unit returns from the power saving state, and, when the power-interruption detecting unit detects the power interruption, transmit a power interruption notification to the OLT. The OLT includes the PON control unit configured to determine, based on the power saving return information, whether the ONU can transmit the power interruption notification when the power interruption occurs in the power saving state.
First claim
Opening claim text (preview).
The invention claimed is: 1. A communication system comprising: optical network units; and an optical line terminal configured to carry out band allocation to the optical network units, wherein at least one of the optical network units includes: a power-interruption detecting unit configured to detect power interruption of the optical network unit; a transmitting and receiving unit capable of being set in a power saving state; and a subscriber-side control unit configured…
